Time to talk about compression ratio's. Here is an comment in the video I am watching.
Vlog coming soon.



Nothing to do with engine speed. Compared to running at a 8:0 compression ratio, you will have more power off boost and when you stay under 18 psi of boost. At zero boost, you'll be making 3.6% more power thanks to the higher compression ratio. When you are at 15psi of boost, you'll be making 0.8-percent more power. Once you go over 19spi of boost, you'll be making less power than the lower compression ratio. At 30psi, you'll be down 2.0-percent in power versus what you would have been making if you kept the engine at 8.0:1. If you are making 600whp with the 10:1 setup, you would have made 612whp with the 8.0:1 setup at 30psi of boost.
